BILLY Connolly wants to have the last laugh on visitors to his grave – with a spooky interactive burial plot.

A pressure pad under the turf would set off a recording of his voice.

The comic was diagnosed with prostate cancer and Parkinson’s disease last year.

Thoughts about his own mortality inspired his new ITV film, Billy Connolly’s Big Send Off. It goes out on Wednesday and examines attitudes to death around the world.

In it, Billy said: “I was going to have ‘Oh Jesus Christ, is that the time already’, but in tiny little letters, about an eighth of an inch high so to see them you’d have to step on to the grave where I would have placed, under the turf, those sensitive pads that you get for people who are breaking into your house.

“And it would activate a sound system and it would say, ‘You’re standing on my balls’.”

Billy, 71, also talks to his pal Eric Idle, from the Monty Python team. Idle expects his song Always Look on the Bright Side of Life would be used at his funeral.

He said: “You know they are going to play Bright Side no matter what I ask for.

“They’ve got to play it because it says, ‘just remember that the last laugh is on you’, so they’ll definitely play that one.”
